Abstract: ABSTRACT OF THE DISCLOSURE           A curved prismatic, Fresnel-type lens primarily used for concentrating sunlight in a solar energy collector.      The lens comprises a substantially smooth, convex outer surface and a plurality of prisms arranged side-by-side along a curve on the inner surface to direct incoming light to a common area.  Each of the individual prisms has a front and back face joined by a bottom face.  The front and back faces of the prisms are oriented such that the angle of incidence of the incoming light with the front face is equal to the angle of incidence of the outgoing light with the back face.  Futher, each of the prisms is arranged along the curve such that they do not obstruct light passing through any adjacent prism.  The bottom face of  each prism is over-extended beyond the path of the light passing through the prism to prevent loss of light due to blockage by the bottom face or the rounded point between the back face and bottom face.      The improved lens is used in combination with a solar energy collector comprising the improved concentrator and a suitable energy receiver for converting incident sunlight into a useful energy output.

Abstract: WASTE HEAT UTILIZATION SYSTEM            Abstract of the Disclosure Power generating plants discharge steam or hot water typical-ly from a steam turbine to a condenser system for the purpose of cooling the discharged fluid prior to its being recirculated. The condenser system receives water from an ambient source pumped using a circulating water pump, said water being elevated to a temperature on the order of 115°F. to 125°F. upon passing through the condenser system.  The condenser system can operate in basically two different states to provide either single pressure, single pass condenser operation when the waste hot water is discharged to the source and not used, or multi-pressure, multi-pass condenser operation to maintain an elevated hot water supply that is fed to a load (utilization equipment).  Valve controls are provided for enabling serial-to-parallel and, vice versa, switching between modes of operation without difficulties and with only a slight drop in load during the transition.  The heated water is temperature controlled to the above-mentioned range.  The system is particularly adaptable to use with a plurality of power plants by combining the discharges of several plants as needed, or by removing plants from the waste heat system when not needed.  A special pressure control is provided at all plants to compensate for variations in water flow occasioned by changes in electric generation.       1.

Abstract: ABSTRACT                      STENCIL DUPLICATOR       An automatic control mechanism for the thickness of an ink layer on a duplicator cylinder employs a sensing roller mounted for movement along a path which extends both peripherally and radially of the cylinder where the ink is to be measured and thus the drag on the ink pulls the cylinder to an equilibrium position where it just maintains sufficient contact with the layer of ink to be subject to that drag whereas any further movement will move it radially away from the ink layer to lose contact.  The pivoting support for the sensing roller engages a switch when an extreme position is attained and this provides an "enough ink" signal.       An adjustable biasing mechanism enables the position of the sensing roller to be additionally subject to a biasing selective manually by the operator to control ink layer thickness and another adjustment in response to the speed of rotation of the duplicator.       In one form, the sensing roller is able to skew so that a sensing switch at one end of the duplicator cylinder may be tripped before the sensing switch of the other end of the cylinder, for the purposes of providing a control which at least to some extent is responsive to local thickness of the layer.  A further possibility envisages providing several different such rollers which between them cover the entire axial extent of the cylinder and thus they are each able to control the application of ink locally.

Abstract: ABSTRACT OF THE DISCLOSURE      A process for producing decorative articles having patterns of surface concavities and convexities (unevennesses) comprises the steps of : 1)  placing into mutual contact and laminating a hardenable decorative material layer and an expan-sion-contraction deformable sheet provided with regions susceptible to expansion-contraction de-formation and regions not susceptible to said de-formation; 2)  causing the deformable sheet to undergo said de-formation under pressure thereby to impart a pattern of unevennesses to the decorative material layer in contact with the sheet; and 3)  causing the hardenable decorative material layer to fully harden.       The sheet deformed under pressure imparts a unique pattern of surface unevennesses corresponding to the two kinds of regions to the decorative material layer.  Decorative articles thus obtained can be ap-plied to a wide variety of uses as materials for decorating architectural exteriors and interiors and as decorative boards.  The degree of surface unevenness can be controlled by adjusting the pressure.  Colored patterns corresponding to the unevennesses can also be formed.
